graph3D->addSeries(series);//创建数据, 墨西哥草帽QSurfaceDataArray *dataArray = new QSurfaceDataArray; //数组dataArray->reserve(N);proxy->resetArray(dataArray);//渐变颜色按钮QLinearGradient grBtoY(0, 0, 100, 0);   //线型渐变grBtoY.setColorAt(1.0, Qt::black);grBtoY.setColorAt(0.0, Qt::yellow);QPixmap pm(160, 20);    //图片QPainter pmp(&pm);//画家pmp.setBrush(QBrush(grBtoY)); //渐变颜色1pmp.setPen(Qt::NoPen);pmp.drawRect(0, 0, 160, 20);ui->btnGrad1->setIcon(QIcon(pm));//渐变颜色按钮1//单一曲面颜色QColor  color=series->baseColor();color=QColorDialog::getColor(color);if (color.isValid()){series->setBaseColor(color);series->setColorStyle(Q3DTheme::ColorStyleUniform);}//选择模式（如剖面图）
graph3D->setSelectionMode(QAbstract3DGraph::SelectionSlice);
//曲面样式（入是否是框架图）

}//选择标识的形状，如一个点，一个三角
QAbstract3DSeries::Mesh aMesh;
aMesh=QAbstract3DSeries::Mesh(index+1);
series->setMesh(aMesh);

三维地形图

Q3DSurface  *graph3D= new Q3DSurface();//三维图表//创建数据代理
QImage heightMapImage(":/map/sea.png");
QHeightMapSurfaceDataProxy *proxy= new QHeightMapSurfaceDataProxy(heightMapImage); //数据代理
proxy->setValueRanges(-5000, 5000, -5000, 5000);QSurface3DSeries *series= new QSurface3DSeries(proxy);//序列
